Motta is a small ball of acid curd from the Valsesia, made with no rennet at all. Raw milk, partly skimmed by letting the cream rise, sours at room temperature for 12–24 hours until it sets like yoghurt. The moist curd is kneaded with salt, pepper, fennel seed and cumin, rolled into balls and eaten fresh or after 1–2 weeks.
Total time across the recorded steps: 7.5 days – 15 days

At a glance
Motta is a small ball of acid curd from the Valsesia, made with no rennet at all. Raw milk, partly skimmed by letting the cream rise, sours at room temperature for 12–24 hours until it sets like yoghurt. The moist curd is kneaded with salt, pepper, fennel seed and cumin, rolled into balls and eaten fresh or after 1–2 weeks. Made in 5 steps over 7.5 days – 15 days. The longest step, ripen on wooden boards, takes 7–14 days (Regione Piemonte 2015).
Motta uses no rennet. The sheets say it began in the lower summer pastures, where the milk sours too much in the warmth; the excess acidity of the milk and the surface cream ruled out normal cheesemaking, so the acid curd was spiced and rolled into balls.
Rind
Irregular, pale yellow to hazelnut; none or slightly mouldy
The regional sheet notes that a well-developed acidity in the finished cheese holds back unwanted microbes. The milk is raw, and the cheese may be eaten just made or after 1–2 weeks. The US CDC says people at higher risk of Listeria infection, including pregnant women, people 65 or older and people with weak immunity, should avoid cheese made with raw milk unless it is heated to 165 °F (74 °C) or until steaming hot.
The ONAF sheet says motta began in the lowest summer pastures, where the milk sours too much in the sometimes high temperatures. In the area's very poor tradition it let people use milk that was too acid, with too much acid cream on top, for ordinary cheesemaking. It is made all year, but the summer-pasture version is the most characteristic.
